Sorry if this has already been covered, but as am struggling to even describe the noise.... searching for it is impossible.

I have an intermittent noise on my 07 TDV8, which seems to come from the passenger side of the car. It seems to be completely random and happens both when cold/hot, driving/stationary. It seems to be nothing to do with the heater system as fan speed has no impact.

The noise is like a moaning and varies in volume, maybe a little like a distant hoover sound, but a little deeper in tone. It is not constant, so may be mmmmm..mmm.mmmmmmmmmm..mm......mmmmmmm, would be a good descriptor.

I know this is random....... as it is intermittent, taking it to a garage is a little difficult.... sods law it will not do it then ! 2011 Stornaway Grey 5.0SC Autobiography

i would have said the FBH, but you say it comes on when hot , so ?... ... - .- -.

FBH is working normally, and makes a different, and more constant, noise. 2011 Stornaway Grey 5.0SC Autobiography

a thought, could it be the cd changer in the glove box, maybe the disc is vibrating causing the humming... ... - .- -.

The passenger seat often does moan, but much louder and more focused.  2011 Stornaway Grey 5.0SC Autobiography

Its unrelated - but I had an irritating rattle in the cabin that I was positive was coming from the passenger side. When SWMBO was in the passenger seat she swore it was coming from the drivers side. It turned out to be sunglasses rattling in the overhead holder (middle) - easy fix!!
The point I'm making is get a passenger in to confirm the location of the noise before you start tearing things apart. You might have already done this but if not it's worth the check. Geoff

Sure there is a post somewhere which references a noise relating to the parking sensors, my 07 does it sometimes, more prevalent after heavy rainfall. It usually lasts a very short period of time and is very intermittent, therefore it remains un-diagnosed in my case. First time I heard it, it was a very peculiar noise which didn't sound like normal engine /suspension noise issues I'd encountered in the past with other cars.

I have the exact same noise, always does it on cod start up after engine running for about 1 min, but then re do it later for no apparent reason! I stopped once and popped the bonnet and was very loud and seem to one from the air box, still haven't diagnosed the problem Range rover tdv8 56. Vogue

Whooshy oil pump?

Had a good hunt around, and not necessarily any further on, but am trying things in order.... Problem with intermittent faults... No idea if fixed or not.

First one was to remove the cassette from auto changer....... No had it since, but early days. 2011 Stornaway Grey 5.0SC Autobiography
